Howdy,
If anybody wants to use their Android to control things, I can bring a few projects to the meeting, that I'm involved with.
I have the
a. IOIO project, that talks to the Android via USB and/or Bluetooth
b. Microchip Development Kit that talks Android thru USB
c. Flyport project, wifi based controller.
All of these projects have self contained
microcontrollers that can be used to manage and control real world devices, using the Android as a user interface...
Nothing like using a $500 phone to control your sprinkler system.....
